Abstract
A new pyrene-modified nucleotide monomer is introduced, wherein pyrene is attached to the 2'-position of arabino-uridine through a triazolemethyl linker. When the monomer is introduced into oligonucleotides, very stable DNA duplexes and three way junctions are obtained. An oligonucleotide featuring two modifications in the center shows four-fold increase in the intensity of the pyrene excimer signal on hybridization with an RNA target but not with a DNA target. The new nucleotide monomer has potential in DNA invader probes as well as in RNA targeting and detection.
